38. Assuming a sample mixture made from sand and sugar had a mass of 53.5 g, and
it was separated using decantation and boiling to remove the water used in the
separation procedure, what is the mass percent of sugar in the sample assuming 35.2
g of sugar was recovered, and 16.0 g of sand was recovered?

A.66%sugar
B.4%sugar
C.30%sugar

39. Using the information from question 38 what is the total percent recovery for the separation? Is the percent recovery greater than less than 100% why might this be the case?

The Mass percent of sugar in the sample was 66% while the Total percent recovery is 95.7%

Equation

An equation is an expression used to show the relationship between two or more variables and numbers.

Given the sample had a mass of 53.5g, hence:

Mass percent of sugar in the sample = (35.2/53.5) * 100% = 66%

Total percent recovery = [(35.2 + 16)/ 53.5] * 100% = 95.7%

The Mass percent of sugar in the sample was 66% while the Total percent recovery is 95.7%
